Coverage Criteria for SIJ Procedures

inv-01: Initial Diagnostic SIJ Injection

Initial diagnostic intra-articular sacroiliac joint injection is considered medically necessary when ALL of the following are met:

Initial SIJ diagnostic criteria: Physical exam demonstrates reproduction of localized sacroiliac joint pain on at least three (3) of the specified provocative tests (distraction/gapping, FABER/Patrick, thigh thrust/posterior pelvic pain provocational, Gaenslen's, SIJ compression, sacral thrust, Yeoman's).>=3 positive tests

provocative tests list from policy

Pain location: Symptoms include pain primarily experienced between the upper level of the iliac crests and the gluteal fold (may refer distally, even below the knee).

Exclude other causes: Clinical findings and imaging studies suggest no other obvious cause of the pain (e.g., central spinal stenosis with neurogenic claudication/myelopathy; foraminal stenosis or disc herniation with concordant radicular pain/radiculopathy; infection; tumor; fracture; pseudoarthrosis; or pain related to spinal instrumentation).

Conservative therapy trial: Pain has persisted despite BOTH of the following: at least four (4) weeks of conservative treatment (e.g., exercise, physical therapy, chiropractic care, or NSAIDs/analgesics) AND continued active participation in a rehabilitative program or home exercise program.>=4 weeks

Injectate and imaging: When criteria met, injections should include anesthetic, corticosteroid, and/or contrast and be performed with CT- or fluoroscopic-guidance with injection of contrast (absent allergy).

See image guidance and injectates sections

inv-02: Initial Diagnostic Injection

Covered when ALL of the following are met

Initial diagnostic intra-articular SIJ injection: Physical exam reproduces localized SIJ pain on at least three (3) specified provocative tests; pain primarily between iliac crests and gluteal fold; clinical findings and imaging exclude other obvious causes; pain persisted despite both at least four (4) weeks of conservative treatment and continued active participation in a rehabilitative/home exercise program.see text

Provocative tests listed: distraction, FABER, thigh thrust, Gaenslen's, compression, sacral thrust, Yeoman's.

inv-03: Repeat Diagnostic Injection

Covered when

Repeat diagnostic intra-articular SIJ injection: Initial diagnostic intra-articular SIJ injection resulted in a positive response with ≥75% reduction in the reported pain for the duration of the local anesthetic.≥75% pain reduction

Repeat diagnostic injection indicated only after prior positive diagnostic block.

inv-04: Initial Therapeutic Injection

Covered when

Initial therapeutic intra-articular SIJ injection: Follows a diagnostic intra-articular SIJ injection that resulted in ≥75% reduction in the reported pain for the duration of the local anesthetic.≥75% pain reduction on diagnostic block

Diagnostic block must be positive to proceed to therapeutic injection.

Injectate and imaging for therapeutic injection: Therapeutic intra-articular SIJ injections should be performed with anesthetic, corticosteroid, and/or contrast under CT- or fluoroscopic-guidance with injection of contrast unless allergic.

See injectates and image guidance requirements

inv-05: Repeat Therapeutic Injection

Covered when ALL of the following are met

Minimum interval: A minimum of two (2) months since the prior therapeutic intra-articular sacroiliac joint injection.2 months

Interval required for recurrence of pain before repeat therapeutic injection.

Prior therapeutic response: The prior therapeutic intra-articular SIJ injection resulted in a positive response with ≥75% reduction in the reported pain for two (2) or more weeks duration.≥75% pain reduction for ≥2 weeks

Functional or medication/service improvement: EITHER an increase in level of function for at least two (2) weeks OR reduction in the use of pain medication and/or additional medical services (e.g., physical therapy/chiropractic care) for at least two (2) weeks.2 weeks

When criteria are met, only one invasive modality or procedure (for example, facet joint injection, epidural steroid injection, or lumbar sympathetic chain block) performed on the same date of service is considered medically necessary. This means multiple invasive procedures for different targets should not be performed on the same day for the same episode of care.

Sacroiliac joint injections performed using ultrasound guidance are considered not medically necessary. In addition, intra-articular SIJ injections that use injectates other than an anesthetic, corticosteroid, and/or contrast agent (alone or in combination) are considered not medically necessary. When criteria are met, image-guidance using fluoroscopy or CT and use of contrast (if not allergic) are the expected techniques.

No explicit exclusion statements beyond those cited in the policy excerpts are provided in the available document text.

Utilization limits apply: no more than two (2) diagnostic intra-articular SIJ injections and no more than four (4) therapeutic intra-articular SIJ injections per SI joint in a rolling 12-month period. For recurrence of pain, a minimum interval of two (2) months is required between therapeutic injections.

Diagnostic or therapeutic SIJ injections that do not meet the policy’s Definitions, General Guidelines, and Indications — including required clinical findings, prior conservative care, appropriate image guidance, and required injectates — are addressed as not meeting the general guidance and may be considered not medically necessary.

No additional explicit 'not medically necessary' determinations beyond those cited in the provided excerpts are included in the available document text.

Provider Actions, Prior Authorization, and Documentation

Prior Authorization

Prior authorization and frequency limits

When criteria are met, only one invasive modality or procedure may be performed on the same date of service, and utilization limits apply: no more than two diagnostic intra‑articular SIJ injections and no more than four therapeutic intra‑articular SIJ injections per SI joint in a rolling 12‑month period; a minimum interval of two months is required between therapeutic injections for recurrence of pain.

Only one invasive modality or procedure per date of service is considered medically necessary.
Maximum of 2 diagnostic SIJ injections per joint (to determine source of pain).
Maximum of 4 therapeutic SIJ injections per SI joint in a rolling 12‑month period.
Minimum 2 months required between therapeutic injections for recurrence.

Prior Authorization

Check plan for prior authorization on listed SIJ codes

Prior authorization may be required for the listed SIJ procedure and related codes per the applicable health plan. Inclusion of a code in the policy's code table does not guarantee coverage or management status—check the member's Certificate/Evidence of Coverage and the health plan for PA details.

Definitions

Intra‑Articular SIJ Injection

TermIntra‑Articular Sacroiliac Joint (SIJ) Injection

DefinitionInjection of contrast (if no allergy), followed by corticosteroid and/or a local anesthetic into the sacroiliac joint under fluoroscopic- or CT-guidance.

PurposeDiagnostic when used to determine if the SIJ is the source of pain; therapeutic when used to treat SIJ pain.

Sacral Lateral Branch Nerve Block

TermSacral Lateral Branch Nerve Block

DefinitionInjection of corticosteroid and/or local anesthetic adjacent to the sacral lateral nerve resulting in temporary interruption of conduction of impulses for analgesia.

Background

The sacroiliac (SI) joint is the synovial articulation between the sacrum and the ilium and can be a source of low back and buttock pain. Diagnostic intra-articular SIJ injections—performed with image guidance and typically including contrast when not contraindicated—are used to determine whether the SIJ is the pain generator. Therapeutic intra-articular injections (usually corticosteroid with or without local anesthetic) are used to treat SIJ-mediated pain after diagnostic confirmation. Clinical diagnosis of SIJ pain relies on history, symptom location (commonly between the iliac crests and the gluteal fold), multiple positive provocative tests, exclusion of other causes by exam and imaging, and response to a diagnostic block.

On This Page

One of these improvements must be documented for repeat therapeutic injection.

Frequency limit: No more than four (4) therapeutic intra-articular sacroiliac joint injections per SI joint during a rolling 12-month period.max 4 per 12 months

Frequency limits apply across rolling 12-month period; see policy for diagnostic injection limits.

Codes listed in the policy (e.g., 27096, G0260, 64451, 64625) may require prior authorization per the applicable plan.
Inclusion of a code in the table does not imply it is under management or that PA is required; prior authorization is not a guarantee of payment.

Note

No explicit prior‑authorization process specified in excerpts

The provided excerpts do not state specific prior authorization processes, forms, or explicit PA triggers; they contain criteria, frequency limits, codes, and bibliographic references but no detailed PA workflow in these chunks.

No explicit prior authorization procedures, required documentation for PA submission, or automatic authorization triggers are present in the cited excerpts.

Documentation Required

Conservative care required before diagnostic SIJ injection

An initial diagnostic intra‑articular SIJ injection requires prior conservative management: pain must have persisted despite at least four (4) weeks of conservative treatment AND continued active participation in a rehabilitative program or home exercise program. Document these treatments and participation.

At least 4 weeks of conservative treatment (e.g., exercise, physical therapy, chiropractic care, or NSAIDs/analgesics).
Continued active participation in a rehabilitative program or home exercise program prior to diagnostic injection.

Documentation Required

Document conservative therapy type and duration

Conservative therapy examples and required duration must be documented prior to an initial diagnostic injection: therapies include exercise, physical therapy, chiropractic care, and medications such as NSAIDs or other analgesics, with a minimum trial of four (4) weeks.

Examples: exercise, physical therapy, chiropractic care, NSAIDs or analgesic medications.
Minimum duration: at least 4 weeks of conservative therapy documented.

Note

No step‑therapy requirements specified

No step therapy or formal step‑therapy requirements are specified in the provided excerpts.

The policy excerpts contain conservative‑care prerequisites but do not define a step‑therapy program or stepwise medication/treatment escalation requirements.

Documentation Required

Required injectates and image guidance for covered injections

When the coverage criteria are met, intra‑articular SIJ injections must include appropriate injectates (anesthetic, corticosteroid, and/or contrast) and be performed under CT‑ or fluoroscopic‑guidance; injection of contrast is required unless the patient is allergic.

Required injectates: anesthetic and corticosteroid and/or contrast agent.
Image guidance: CT or fluoroscopic guidance with injection of contrast (absent allergy).

Documentation Required

Required clinical documentation to support SIJ injection

Clinical documentation should include a positive provocative physical exam with at least three (≥3) specified tests, symptom distribution primarily between the iliac crests and the gluteal fold, and exclusion of other obvious causes by clinical findings and imaging.

Document ≥3 positive provocative SIJ tests (distraction/gapping, FABER, thigh thrust, Gaenslen's, compression, sacral thrust, Yeoman's).
Document pain location between the upper iliac crests and gluteal fold (may refer distally).
Document exclusion of other causes (e.g., central spinal stenosis, foraminal stenosis/disc herniation with concordant radiculopathy, infection, tumor, fracture, pseudoarthrosis, or instrumentation‑related pain).

Note

Some excerpts lack explicit documentation requirements

Certain document excerpts contain references and guideline citations but do not specify explicit documentation items or submission requirements; these bibliographic sections do not replace the clinical documentation required by the criteria.

No explicit additional documentation or PA submission checklists are provided in the cited reference sections.

Denial Risk

Case‑by‑case coverage determinations may increase denial risk if plan terms/collateral info are missing

Coverage determinations are made on a case‑by‑case basis and require consideration of the member's benefit plan terms, applicable laws and regulations, and collateral materials; absence of plan‑specific information or supporting collateral materials may increase the risk of denial.

Medical necessity determinations are individualized and depend on benefit plan terms and applicable laws/regulations.
Provide collateral clinical materials as needed to support medical necessity determinations.

Denial Risk

Denial risk for procedures that do not meet criteria or exceed frequency limits

Diagnostic or therapeutic intra‑articular SIJ injections that do not meet the Definitions, General Guidelines, and Indications sections (e.g., missing required provocative test documentation, conservative therapy trial, injectate/image‑guidance standards, or exceeding frequency limits) are considered not medically necessary and may be denied.

Procedures performed without meeting required criteria (definitions, guidelines, indications) may be denied.
Exceeding stated frequency limits (more than 2 diagnostic or more than 4 therapeutic injections per joint in 12 months) may result in denial.

Note

No explicit authorization or denial triggers present in excerpts

The provided excerpts do not include explicit authorization or denial triggers (e.g., automatic system flags or specific claim edits) in the cited chunks; authorization or denial actions are based on the policy criteria and plan‑specific processes rather than explicit triggers in these excerpts.

No explicit automated authorization/denial triggers are described in the bibliographic/reference excerpts.

Duration of analgesia depends on dose, concentration, and agent used.
